Title: Bioactive materials, methods of making bioactive materials and method of use thereof
Inventor: DIBENEDETTO ANTHONY T
IPC: A61L27/22
Filed: 2002-10-25
Granted: 2012-01-03
Abstract: A bioactive material is made using fibroin solutions and suspensions that can be used alone or as a composite with particles such as core/shell particles.  The material is designed to support the constructions, repair, regeneration or augmentation of bone and other tissues of the body. The solutions and suspensions can be loaded with core/shell-type particles comprising inorganic core materials that are coated with biodegradable polymers with an outer coating of a calcium phosphate precursor. The fibroin solutions, suspensions, and composites can be injected to fill cavities or to replace missing tissue.  After injection, the materials can produce a scaffold capable of promoting tissue regeneration while degrading. The degradation of the particles, when present, can generate additional porosity within the scaffold and release other compounds in a controlled manner to enhance growth and activation of the cells necessary for tissue repair. The ability to inject the fibroin solutions, suspensions and composites can reduce the need for many types of surgical procedures that are used to replace or repair bone and other tissues.

Abstract: The invention is directed to a handheld toothbrush (1) with a brush head (4) having a forward free end (5) and a rearward portion (6). Adjoining the rearward portion (6) is a handle (2). Provided at the forward free end (5) of the brush head (4) is at least one bristle tuft (21) of a first set (8), which extends upwardly away from the bristled surface (7) of the brush head (4). Adjoining the first set (8) in rearward direction is a second set (9) of bristle tufts (25, 26), which is comprised of several bristle tufts (25) which protrude from the surface (7), are arranged serially on a ring area, and extend in the circumferential direction of the ring area at an angle of inclination relative to the surface (7) of the brush head (4), said second set comprising in addition at least one further tuft (26) that protrudes from the surface (7) and extends within the bristle tufts (25) arranged on the ring area. According to the invention a third set (10) of bristle tufts (28) adjoins the second set (9) of bristle tufts (25) in the direction towards the rearward portion (6), said third set being comprised of several bristle tufts (28) which protrude from the surface (7) and are arranged serially on a ring area. The bristle tufts (28) of the third set (10) are inclined in the circumferential direction in opposition to the direction of the bristle tufts (25) of the second set (9).  As a result these bristle tufts (25, 28) are capable of penetrating optimally between this user's teeth, hence ensuring a better cleaning result.

Abstract: According to the invention, the flexible linking device is located between a flexible bogie chassis girder and an axle box arm, and it is characterised in that the stiffness of the link is greater vertically (Z) than in the other two horizontal (X, Y) directions. This allows the bogie chassis girder to be de-coupled from the axle box and thus to reduce the demands on the interfaces of these parts when the bogie chassis moves transversally and vertically in relation to the axles. It also presents the advantage of allowing relative movement between the girder and the axle box.

Abstract: A reaction apparatus for producing silicon has a reaction container that forms space surrounded by a vertically extending wall and heating means capable of heating at least part of a surface of the wall including the lower part of the wall that faces the space to a temperature higher than the melting point of silicon. Raw material gas for silicon separation is circulated from the upper part to the lower part of the space of the reaction container. Because the space of the reaction container has a slit shape as seen in a transverse cross-section, reduction in raw material gas reaction rate and forming of a by-product are improved, and productivity is improved remarkably.
